Intel 80188
The Intel 80188 microprocessor was a variant of the Intel 80186. The 80188 had an 8-bit external data bus instead of the 16-bit bus of the 80186; this made it less expensive to connect to peripherals. The 16-bit registers and the one megabyte address range were unchanged, however. It had a throughput of 1 million instructions per second. Intel second sourced this microprocessor to Fujitsu Limited around 1985. Both packages of Intel 80188 version were available in 68-pin PLCC and PGA in sampling at third quarter of 1985. The available 80C188EB in fully static design for the application-specific standard product using the 1-micron CHMOS IV technology. They were available in 3- and 5-Volts version with 84-lead PLCC and 80-lead EIAJ QFP version. It was also available for US$15.15 in 1,000 unit quantities.
